AcoustiSens MT-130 Wideband Single-Mode Optical Fiber (P/N: GS88145) is a vibration sensing fiber with optimal performance for Distributed Acoustic Sensing (DAS) systems in applications where elevated temperatures may be encountered. Using a waveguide design based on the ITU-T G.657.A1 telecom-grade singlemode standard, AcoustiSens MT-130 Wideband fibers significantly increase Rayleigh backscatter while maintaining low attenuation to improve Optical Signal to Noise Ratio (OSNR).
Furthermore, the AcoustiSens MT-130 Wideband fibers provide bend-insensitivity and expand the operating wavelength band (1536 – 1556 nm) ensuring interoperability with all known DAS interrogators. Without the need for changes in interrogation equipment or complex optical amplification schemes AcoustiSens MT-130 Wideband is a drop-in fiber replacement that provides greatly improved sensing performance with OSNR orders of magnitude better than telecom-standard fibers. This translates into significantly improved Acoustic Signal-to-Noise Ratio (ASNR) in DAS systems. Due to its waveguide design and thermally stable coating, AcoustiSens fibers are suitable for continuous use up to 130 °C and splice compatible with G.657.A1 and G.652.D optical fibers. This ensures smooth integration with commonly deployed DAS sensing solutions and improved reliability with up to 10 years continuous use.*
